Celebrity Dirty Laundry is under the impression that not only are Rob and Kristen an item again, but that Katy Perry is going to have to cut ties with them because of this. The site presumes that Perry and Pattinson "clearly hooked up several times" after he and Kristen broke up and that there's no way Kristen will ever be able to forgive her for that. Hence, Perry will be kicked out of their little group of friends so Robsten can live happily ever after.

I'm certainly wont to take this story with a grain of salt, as I'm not even sure I believe Katy and Rob ever got it on (the pop star admitted to farting in front of the Twilight hottie-- is that something you'd do in front of a dude you were hooking up with?), but if you buy into the ol' "where there's smoke, there's fire" theory, sounds like something is brewing with Kristen and Rob again.

One thing we can all count on, though, is that it's highly unlikely that either of the actors will ever come out and address the rumors. If they're smart, they'll keep their relationship under wraps, as clearly, being a public item does not behoove them.
